For more information about item identifiers see the item identifiers section.


Primary Identifier

The primary identifier is the SQL server or instance name for example CORPSQL or CORPSQL\Intranet depending on whether the instance is running as the default or named instance.


Secondary Identifier

For non-clustered on-premises installations of SQL Server the computer serial number is used, otherwise this identifier is not used. The host information optional component is required to gather the serial number, therefore changing host information setting can cause duplicate items to be created.


Tertiary Identifier

Not used.
